We start to address task 1 by classifying the eight known classes. It is known from the previous ISIC challenges that the most successful approaches are those based on ensemble of classifiers [1]}. For this reason, we adopted the following convolutinal neural networks (CNNs): SENet [2]}, PNASNet [3]}, InceptionV4 [4]}, ResNet-50/101/152 [5]}, DenseNet-121/169/201 [6]}, MobileNetV2 [7]}, GoogleNet [8]}, and VGG-16/19 [9]}.
